Arlo security cameras and HEVC codec

I am using Arlo security cameras which store the video captures as MP4 files. The Arlo app has video playback feature that works in Chrome or Edge but does not work in FireFox. From what I have been abe to glean from searches, Arlo uses HEVC Codec that FireFox either isn't compatible with or is lacking the codec. Any suggestions?

Short of abandoning FireFox and going with Edge, is there a workaround?

Locking thread to prevent further spamming.


Noticed some new work being done in Firefox 120 on HEVC support, so you may want to keep an eye on this (unlocking for now).
